| The
function of a Tester for CR injectors is to provide desired signal
to drive the solenoid in the CR injector being tested. Testers of
two models have been designed, one for driving single CR injector
and the other for driving up to 6 injectors.
The
tester has two working modes, continuous injection and single
injection.
The
CR injector tester is applied for CR system repair in two aspects:
(1)
To test if the CR injector is still function
To
connect a CR injector to a high-pressure fuel source by a
high-pressure fuel line and to the CR tester by harness. The tester
is set to continuous injection mode. The CR injector is in normal
condition, if it is capable to inject fuel under the driving signals
by the tester.
(2)
To test injector spray atomization
To
connect a CR injector to a high-pressure fuel source by a high
pressure fuel line and to the CR tester by harness. The tester is
set to single injection mode to allow observing the nozzle spray
pattern to judge if the nozzle is normal or orifice plugged.
